To ill whom it may conbcen: t p

Be it known that I, HARRY C. KNOX, a citizen of the Un'ited States ofAmerica, residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements inBox-Fasteners;

and I do hereby declare that the following is a full, clear, and exactdescription ofthe invention, such as will enable others to AI'nake anduse thesame, reference being had to the accompanying drawings, forming apart of this specification.

The object of the present invention is to enable the securing devicewithin the box which automatically engages the bolt in a box-fastener toincrease the resistance to the power applied to withdraw the bolt.

The invention consists in the novel construction and combination ofparts, such as will be first fully described, and specifically pointedout in the claims.

In the drawings, Figure l is a view in perspective, showing the novelbox-fastener applied to a box, the parts of which box are in dottedlines. Fig 2 is a sectional view of a portion of the top and side andnarrow end of the box, showing one of the corner-brackets and thenon-rotating fastening-bolts to the top, sides, and ends of the box.Fig. 3 is a plan view of the top of the bracket, and Fig. 4 is a detailview of the bolt. Fig. 5 is a broken detail view of the end of the box,showing the top of the bracket forming an integral part thereof.

Similar letters of reference indicate' corre-- sponding parts in all theigures.

Referring to the drawings, A represents the bracket which is employed inthe fastening of the parts of the box together and which consists of theside plates ad, rectangular in form and extending at right angles toeach other, and a top plate a', also rectangular in form and extendingfrom one side a to the other side, with which sides the top is rigidlyconnected. In the top plate a are separate bolt-fastening catches orclips as 0,3,which are integral with-the said plate. Said catches areformed by the separation of a narrow strip from the top a of thebracket, which is accomplished by cutting through said top a.' in twoparallel lines a short distance apart. The strip is then cut orseparated transversely at the point a4, intermediate its length, so asto' form two catches Or short strips a3 CL3, which are depressed by thebolt and the free ends of said strips inclined or beveled to an edge. Inthe sides a ct of the bracket are clips d3 as, which are formed in thesame manner as in the top d. I

i B represents the non-rotating fasteningbolt, consisting of the shank band head b'. In the lower end of the shank and b upon opsite sides areratchet-teeth b2, extending in a transverse direction thereto andthewidth of the shank. At the extreme lower end of the bolt the sides ofthe bolt are wedge-shaped or inclined downwardly to a point, as at b3.

C represents the box, which consists of the sides c c, ends c c', bottomc2, and top or cover c3. In the cover c3 of the box in a vertical linewith the point of separation a4 of the catches a3 a3 of thecorner-bracket A is au opening or perforation c4, adapted to receive theshank b of the bolt B. sides of the box and extending toward the catchesas a3 are similar openings, as described, of the perforations or openingc4.

In the assemblage of the parts of a box the brackets A are. placedwithin each angle formed by the sides and ends, those employed in thebottom of the box being reversed in position. The Shanks b of the boltsB are then inserted within the perforations or openings inthe sides andends, and the wedgeshaped ends b3, coming into contact with the catchesa3 a3, force the said catches inwardly in position, the heads of thebolts being4 brought close against the outer side of the ends and sidesof the box and the ends of the catches or clips as a3 engaging with theteeth 0r serrations b2 on the shank of the bolt, thus preventing thewithdrawal of the bolt. The top and bottom of the box are then securedto the brackets with bolts B in like manner, thus making the contents ofthe box inaccessible without breaking the top or sides, and thuspreventing unauthorized tampering with the contents of the box. With thenovel box-fastener the contents of a box remain sealed, and any powerapplied to the head of the bolt will be resisted by the clips a3 a3, thepower tending to draw the clips more rmly against the sides of the bolt.

The fastening device may be applied to any IOO box and for the securingof boxes with hinged p covers.

The'top ct of the bracket may be employed without the sides, in whichcase the top of the bracket may bev formed, especially in boxes withmetal sides, from an integral part of the sides. The catches ai as maybe tempered, so as to recoil when bent downwardly in position by thefastening-boit.

Having fully described my invention, what I now claim as new, and desireto secure by Letters Patent, is-

1. A boX having suitable perforations and corner-plates within the box,non-rotating bolts each having a. head and a shank provided Withratchet-teeth, and longitudinallyextended .spring lips or catches uponsaid plates, havingtheir free ends inclined to an edge and adapted toengage with the ratchetteeth upon the Shanks of said bolt.

2. A box having suitable perforations and a corner-bracket having va topand a non-rotating bolthaving a head, and a shank provided withratchet-teeth upon opposite sides thereof, said top ofV the brackethaving longtudinally-extended spring lips or catches forming an'integral part thereof and the free ends of said stripsinclined to anedge.

3. A box having suitable p'erforations and a corner-bracket having a topand sides eX- tended at right angles to each other and adapted to securethe parts of a box together, nonrotating fastening-bolts each having ahead and a shank provided with ratchet-teeth upon opposite sides, andawedge-shaped lower end, and separate lips or catches integral with thetop and sides of said bracket, the free edges of which are inclined toanedgev and engage with the teeth on the shanks of said bolts.
